Reference
1st test solution: c=1159 mg/L, age of solution = 112 min.
Arithmetic mean from 6 measurements = 39.0 +/- 0.1 mN/m
2nd test solution: c=1061 mg/L, age of solution = 170 min.
Arithmetic mean from 6 measurements = 40.7 +/- 0.1 mN/m
Arithmetic mean of 2 test solutions = 39.9 +/- 1.2 mN/m
Arithmetic mean corrected by calibration factor = 40.4 mN/m
Description of key information
